The difference between antifluorite and fluorite is that anti- fluorite refers to an anion array with tetrahedral cations, whereas fluorite has the inverse arrangement with a ccp cation array and tetrahedral anions.
What is fluorite type structure?
From Wikipedia, the free encyclopedia. In solid state chemistry, the fluorite structure refers to a common motif for compounds with the formula MX2. The X ions occupy the eight tetrahedral interstitial sites whereas M ions occupy the regular sites of a face-centered cubic (FCC) structure.
How are cations and anions arranged in FCC?
Very large cations occupy cubic holes in a cubic anion lattice, cations of intermediate size tend to occupy the octahedral holes in an fcc anion lattice, and relatively small cations tend to occupy the tetrahedral holes in an fcc anion lattice.
